POSPac MMS provides the smoothed best estimate of trajectory (SBET) that is necessary for Optech's post processor to develop the point cloud from the LiDAR missions. The point cloud is the mathematical three dimensional collection of all returns from all laser pulses as determined from the aerial mission. At this point this data is ready for analysis, classification, and filtering to generate a bare earth surface model in which the above ground features are removed from the data set. The point cloud was manipulated within the Optech software; GeoCue, TerraScan, and TerraModeler software was used for the automated data classification, manual cleanup, and bare earth generation from this data. Project specific macros were used to classify the ground and to remove the side overlap between parallel flight lines. All data was manually reviewed and any remaining artifacts removed using functionality provided by TerraScan and TerraModeler. The Baldwin County project (G10PD02126) is immediately adjacent to the NGOM Mobile Bay LiDAR project (G10PD00578). A manual review was performed to ensure that the two datasets tied together as seemlessly as possible. Revisions were made to both the LAS and breakline datasets as needed in order to achieve a smooth transition between the two datasets. NGOM Mobile Bay data was used to produce full tile deliverables on the eastern edge of the Baldwin County West dataset and the western edge of the Baldwin County East dataset. Upon completion of the Baldwin County deliverables, revised copies of the NGOM deliverables that border the Baldwin dataset will be provided in order to ensure that the two datasets agree with each other. All Class 2 LiDAR data inside of the collected breaklines were then classified to Class 9 using TerraScan macro functionality. A buffer of 1 meter was also used around each hydro flattened feature. The breakline files were then translated to ESRI Shapefile format using ESRI conversion tools. Data was then run through additional macros to ensure deliverable classification levels matching LAS ASPRS Classification structure. GeoCue functionality was then used to ensure correct LAS Version. In house software was used as a final QA/QC check to provide LAS Analysis of the delivered tiles.dateTime: DateTime: 2011-01-01T00:00:00processStep: (LE_ProcessStep)description: The NOAA Coastal Services Center (CSC) received topographic files in LAS format. The files contained lidar elevation and intensity measurements. The data were received in UTM Zone 16 (NAD83) coordinates and were vertically referenced to NAVD88 using the Geoid09 model. The vertical units of the data were meters. CSC performed the following processing for data storage and Digital Coast provisioning purposes: 1. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid09. 2. The topographic las files were horizontally converted from UTM coordinates (m) to NAD83 Geographic coordinates (dd). 3. ASPRS Class 11 (Witheld) was changed to Class 13 (Witheld). 4. The data were converted to LAZ format.dateTime: DateTime: 2012-12-01T00:00:00processor: (CI_ResponsibleParty)organisationName: DOC/NOAA/NOS/OCM > Office for Coastal Management, National Ocean Service, National Oceanic and Atmospheric Administration, U.S. Department of CommercecontactInfo: (CI_Contact)phone: (CI_Telephone)voice: 843-740-1200address: (CI_Address)deliveryPoint: 2234 South Hobson Ave.city: CharlestonadministrativeArea: SCpostalCode: 29405-2413electronicMailAddress: coastal.info@noaa.govonlineResource: (CI_OnlineResource)linkage: http://coast.noaa.govrole: (CI_RoleCode) processorprocessStep: (LE_ProcessStep)description: The NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp transfer from the NOAA Coastal Services Center. The data are currently
being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are archived in LAS or LAZ format.
The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of
LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to
the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights.dateTime: DateTime: 2013-03-28T00:00:00processor: (CI_ResponsibleParty)individualName: Mike SutherlandorganisationName: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of CommercecontactInfo: (CI_Contact)phone: (CI_Telephone)voice: 303-497-6120facsimile: 303-497-6513address: (CI_Address)deliveryPoint: NOAA/NESDIS/NGDC E/GC1 325 Broadwaycity: BoulderadministrativeArea: COpostalCode: 80305-3328country: USAelectronicMailAddress: mike.sutherland@noaa.govhoursOfService: 7:30am-5:00pm Mountainrole: (CI_RoleCode) processorreturn to topmetadataMaintenance: (MD_MaintenanceInformation)maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) annuallydateOfNextUpdate: 2014-03-28maintenanceNote: This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2013-01-04 version of the FGDC RSE to ISO 19115-2 for LiDAR transform.maintenanceNote: Translated from FGDC 2013-03-28T14:16:36.345-06:00
